The Nature Principle

“Today, the long-held belief that nature has a direct positive impact on human health is making the transition from theory to evidence and from evidence to action. Certain findings have become so convincing that some mainstream health care providers and organizations have begun to promote nature therapy for an array of illnesses and disease prevention. And many of us, without having a name for it, are using the nature tonic. We are, in essence, self-medicating with an inexpensive and unusually convenient drug substitute. Let’s call it vitamin N–for Nature.”
